In this work, density functional calculations are performed to systematically study a series of finite and infinite hydrogenated cluster-assembled silicon nanotubes (SiNTs). It is found that stable one-dimensional SiNTs with formula $Si_{m(3k+1)}H_{2m(k+1)}$ can be constructed by proper assembly of hydrogenated fullerene-like silicon clusters $Si_{4m}H_{4m}$. The stability is first demonstrated by the large cohesive energies and HOMO-LUMO gaps.
